Abstract

Antenne à circuits imprimés qui comprend un premier élément doublet allongé (12) à alimentation par l'extrémité, placé sur une face d'un substrat diélectrique (10). Un second élément doublet (16, 17) est placé sur la face opposée du substrat diélectrique. Le second élément doublet comporte des premier et second éléments allongés (16, 17) disposés de chaque côté de l'axe longitudinal du premier élément doublet, tels que vus à travers le substrat. Un plan (14) de sol sur la seconde face du substrat est connecté aux premier et second éléments (16, 17) à une distance d'une extrémité libre du premier élément doublet correspondant pratiquement à un quart de longueur d'onde de la fréquence (ou fréquence centrale) concernée. Les premier et second éléments (12) ont une longueur correspondant à un quart de longueur d'onde et peuvent être inclinés par rapport au premier élément doublet (12) ou s'étendre parallèlement à ce dernier (figure 4 - non représentée). Des paires d'antennes à circuits imprimés peuvent être connectées à des éléments de commutation pour former des structures (figure 5 - non représentée) diverses d'antenne.
